HomeWater is a waterway monitoring mobile app. I was in charge of the app back end, writing the API and background services. The data service part took care of fetching data from public sources, parsing, filtering, and storing it. Web scrapping techniques were used to fetch the data. The sources used different formats varying from HTML to CSV. This way, there was a parser for each one. All data were then filtered and shaped into JavaScript objects following a single convention to finally be stored in the database.

Namecheap for Education
A website where students can register domains for free or at a lower cost, depending on the extension (TLD) they pick. I maintained the website for around five years. During this period, I was able to refactor most of the features, introduce unit tests, and improve overall performance.
The main website for DataStax. As a full-stack engineer in the marketing team, I maintained the legacy website based on Drupal and participated in the migration to Next.js/ The latter included the development of migration scripts that connected both to Drupal and Sanity APIs.
